So, I am indebt to cousin Sheila Van De Riet for sending me some photos of Sarah and Herman's gravestones. As you can see, they didn't even spell the last name consistently, kind of funny.
I also quizzed Dr. Briganti today when he came over to pick up his daughters. He said that nowadays you would diagnose Myocarditis with a biopsy and not sure how they would have diagnosed it for sure back then. When I asked him what symptoms she would have noticed that might have brought her to the doctor and hospital in the first place, he said that it usually would not have been accompanied by chest pains like a heart attack, but definitely shortness of breath and a general worn-out feeling. Sarah also (now I can't remember if this part was referring to the toxic adenoma thyroid)may have had some water retention going on in the legs.
